2 Claims.

This invention relates to a work holding apparatus and more particularlyto a device for supporting such articles as finished shell forgings, or

the like, during the final step of painting the outer surfaces thereof.

In this operation it is customary to mount the workpiece on a travelingconveyor by which it is carried past paint sprayers, or the like, wherethe outer surface is covered with a protective coating of paint. In thecase of shell forgings and similar articles it is usually desirable torotate the workpiece during its travel to provide an even coating aroundits entire surface, and at the sametime to protect the interior againstthe ingress of any paint.

An object of this invention is to provide a support for workpiecesconstructed and arranged to permit easy attachment to and detachmentfrom a traveling conveyor, or the like, and also to permit rotation ofthe workpiece to be rotated during its travel. A further object is toprovide a device for supporting shells during the painting thereofarranged to seal the open end of the shell to protect the interiorthereof against possibility of any paint being sprayed therein. Theseand other objects are accomplished bythe present invention, oneembodiment of which is illustrated in the accompanying drawing in whichthe single figure is a sectional view through a work support constructedin accordance with one embodiment of this invention and showing a shellforging secured in place thereon.

As illustrated, the invention comprises a hanger l having means such asan eye II to permit its ready attachment to and detachment from asuitable conveyor or the like, not shown. A shell supp rting collar I2is rotatably mounted on the lower end of the hanger In between a collarpositioning shoulder I3 and a collar supporting ball bearing l4 held inplace at the lower end of the hanger by a nut l5 or other securingmeans.

The rotatable collar 12 is provided with shell securing means such asthreads l6 adapted to engage threads I! formed within the open end ofthe shell forging l8, and the collar is so shaped as to form a closureplug for the open end of the shell. In the illustrated embodiment, thecollar is provided with a circular flange I9 at its upp r edge whichseats in the countersink 2D in the shell opening so as to form a sealpreventing the ingress of paint or the like into the shell cavity. Meanssuch as handle bars 2| are mounted on the top of the rotatable collar insuch a position as not to interfere with the securing of shells thereon,and extend outwardly from the collar to a, point where they can begrasped for manually imparting rotation to the collar l2 and itssupported shell by spinning the same.

The handle bars 2| have vertically extending ends 22 seated in sockets23 and welded or otherwise secured in place.

In operation, a shell I8 is secured on the collar l2 by threading thecollar into the open threaded end of the shell cavity. In order toprotect the rifling band 24 against painting, a protective band orcollar, not shown, is secured in place around the rifling band. It willbe apparent that the hanger l0 can be easily mounted upon a suitablehook or the like extending downwardly from the conveyor. Painting isusually accomplished by spraying and rotation can be easily imparted tothe shell during the painting operation by gripping and whirling thehandle bars 2|, the ball bearing l4 permitting the rotation to continueunder its own momentum for a substantial time as the shell 18 functionsin the manner of a flywheel to maintain rotation for a prolonged period.

It will be obvious that the invention can be variously modified andadapted within the scope of the appended claims.

What is claimed is:

1. Apparatus for supporting open-ended articles during painting thereof,comprising a hanger, a collar rotatably supported on said hanger andadapted to close the open end of an openended article, means forsecuring the article to said collar, and means extending outwardly fromsaid collar to impart rotation thereto.

2. Apparatus for supporting open-ended articles during painting thereofcomprising a hanger having means at one end for easy attachment to anddetachment from a conveyor', an article supporting member rotatablymounted on said hanger, means for securing the open end of an open-endedarticle to said member so as to close said end against ingress ofliquid, and a handle bar extending outwardly from said member forimparting rotation thereto.
